I want to talk about how 70CM propagates in canyons compared to 2m. Maybe the topic for a different thread? I had a nice conversation about it with Nathaniel at Blue Notch last year and am thinking maybe we should switch freq's when we are in tight terrain? at least try it once?

This should be similar most places AFAIK, I don't think there's any band plans that use other than 5MHz splits and 25KHz spacing for analog voice.

There are 24 simplex FM, 119 5MHz repeater pairs, 59 aux 5MHz repeater and whole bunch of narrow band (digital) 12.5KHz simplex, pairs and data. There is 30MHz of spectrum allocated to amateurs that is (1) VERY commercially desirable and (b) largely silent.

We have 4 channels designated for 2m since that's the most common radio, particularly in mobile rigs (2m), which is all most were getting when the club first got into ham radio. There currently isn't a designated Rising Sun 70cm frequency, and while there could easily be it wouldn't apply to likely 60% of our licensed operators here. not because of band privilege, but equipment.

And yes, you hit it the theme of the thread here is exploring just that- does 70cm propogate better in the mountains (and canyons) than 2m.. and my answer is I don't know, but I'm willing to try!

So Tim, let's try a 70cm channel tomorrow and see how it works. I will monitor 460 and the denver repeator for any RS members. If you are out and about we can try 70cm just LMK what channel. I will be on the south side of town so not sure of reception.

No, it does not and that's the point. It is more easily absorbed by terrain and does not multipath as badly as VHF, is less likely to duct in the troposphere, so less interference and less chance for random DX. The low side of UHF is more VHF-like than VHF.

Like I mentioned, I usually ragchew on the RMRL's 449.450/-5MHz/103.5 and I suggest using 446.000MHz simplex if you want to check paths since there might be people listening on that.
